76.2mm Clear Aperture 8R/92T, Pellicle Beamsplitter

Product Family Description

• No Ghost Images from Second Surface Reflections
• No Chromatic Aberration with Converging Beams
• No Change in Optical Path Length
• Pellicle Beamsplitters for the Infrared (IR) Also Available

Pellicle Beamsplitters are very thin nitrocellulose membranes bonded to lapped aluminum frames. They feature no ghost images from second surface reflections. To ease system integration, these beamsplitters offer mounting holes on the underside of the frame. Pellicle Beamsplitters are resistant to mechanical shock or climate variations but must be protected from dust and spray to avoid damage to the pellicle membrane. Please note, environments with a high level of humidity (>55%) can cause a temporary loss of tension in the pellicle membrane. The membrane will revert to normal tension if humidity is lowered. 

Note: Extra care must be taken when handling.
